Find where any IP address or website is: country, city, ISP, ASN, VPN flags and blacklists, on a map. Works for IPv4, IPv6, domains and up to 100 IPs at once - a free IP country checker that also explains private addresses. Need the owner of a domain? Try the WHOIS Lookup.

Asking the internet where it left its keys
Reading your list...
Checking where a website is hosted? Enter its domain, then look up the owner with the WHOIS Lookup or grab a picture of the page with Website Screenshot.
Every lookup returns the same set of fields.
| Field | What it tells you |
|---|---|
| Country, region, city | Where the network that owns the IP is registered or routed. City is an estimate. |
| ISP and organisation | The internet provider, and the company the block is assigned to - often the same. |
| ASN | The autonomous system number - the network that announces this IP on the internet. |
| Reverse DNS | The host name set for the IP. "Verified" means it points back to the same IP. |
| Connection type | Residential, mobile, datacenter or VPN/proxy, from database flags and the provider name. |
| Blacklists | Whether the IPv4 is on a spam or botnet DNS blacklist - useful before sending email. |
IP geolocation finds the network, not the person.
A few setups move that network far from the user.
The map pin marks an area, not a building. Treat the city as a good guess and the country as reliable.
Some ranges never appear on the public internet, so they cannot be located.
Look one up and the tool tells you what it is for instead of failing.
| Range | Used for |
|---|---|
| 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 | Private home, office and cloud networks |
| 100.64.0.0/10 | Carrier-grade NAT inside your provider |
| 127.0.0.0/8, ::1 | Loopback - the device itself |
| 169.254.0.0/16, fe80::/10 | Link-local addresses, cloud metadata |
| fc00::/7 | IPv6 private (unique local) networks |
| 192.0.2.0/24, 2001:db8::/32 | Examples in documentation |
Want to work out a range? Type it with its prefix, like 192.168.1.0/24, and the CIDR calculator shows the first and last address and the host count.
IPv4 addresses are four numbers, like 203.0.113.42 - about 4.3 billion in total, and long since handed out.
IPv6 addresses are eight groups of hex digits, like 2001:db8::1, with room for every device for the foreseeable future.
Many connections have both. The address shown at the top is the one your browser used to reach us. Keep your own accounts safe while you are at it with a strong password from the Password Generator.
The country is right for about 95-99% of addresses. The city is right for roughly 50-80%, depending on the country and the provider.
An IP address shows the area of the network that owns it - never a street address or a person.
Mobile carriers, VPNs, corporate networks and carrier-grade NAT route your traffic through a gateway that can be far away - the location shown is that gateway.
Databases also lag for a few weeks when providers move address blocks between regions.
Yes. Enter a domain or paste a full URL and the tool resolves it, then locates the first address. Every address the domain uses is listed, so you can check each one.
Sites behind a CDN show a CDN server, not the origin. For the owner of a domain, use the WHOIS Lookup.
They are private and special addresses. 192.168.x.x, 10.x.x.x and 172.16-31.x.x are used inside home and office networks, and 127.0.0.1 is your own device.
Millions of networks reuse them, so they have no public location. The tool tells you which range an address belongs to and what it is for.
Yes. Switch to Bulk and paste up to 100 IPs or domains, one per line or separated by commas. Turn on Extract IPs from text to paste a whole log file.
Export the table as CSV or JSON - open it in the CSV Viewer or JSON Viewer.
It shows the VPN, proxy and hosting flags from the location database, recognises common VPN providers by name and checks IPv4 addresses against four DNS blacklists.
No tool catches every VPN, and datacenter IPs that relay traffic - like public DNS servers - are sometimes flagged too.
Yes. Full and shortened IPv6 addresses, [IPv6]:port and IPv6 CIDR ranges all work. IPv4-mapped addresses such as ::ffff:8.8.8.8 are located as the IPv4 inside them.
Blacklist checks are IPv4-only, because most blacklists are.
Results are cached on our server for up to 4 hours so repeat lookups are fast, then deleted. We do not keep a log of who looked up what.
